The molecular sizes of histamine H1-receptors of rat, rabbit, human, pig, guinea-pig, chicken, dog, and bovine liver were investigated by radiation inactivation and determined to be 100,000 to 160,000 daltons in all the animals examined. Statistical analysis showed that the hepatic H1-receptors have a common size of 128,000 +/- 63,000 daltons. Saturation analysis showed that the [3H]mepyramine binding constant was not changed by irradiation, while the binding capacity decreased with increase in the radiation dose.
